The following week.
During the first two days, because his Five-dimensional Ability Stats had not yet reached their limit under the buff of 'Two-Phase Divine Power', Levi did not employ the Valkyrie Class Card. Instead, he personally presided over the Elsoth Ruins in his main body.
For the subsequent days, he handed over the work of researching the Creature and Pitch-black Divine Power to Ortlinde.
During this period, Filvis was tormented to the point of mental collapse, dying twice. However, each time, shortly after entering the Reincarnation System, she was dragged back by Levi spending Valis Vouchers.
What followed was a smooth and seamless operation of incarnation, severing limbs, pulling out her tongue, and crushing bones.
It left this Banshee alive but not for long, dead but not thoroughly.
On a hospital bed built of marble, the black-haired elf's face was haggard, her eyes lifeless.
In contrast, the color of the Magic Stone embedded in her chest became increasingly deep and turbid.
Levi was not a pervert; he had no interest in torturing others.
But through the experiments of the past few days, he had roughly determined that the high-dimensional energy he had temporarily named 'Pitch-black Divine Power' had a lower-tier substitute—let's tentatively call it 'Dark Mana'—which existed within the Magic Stone.
Furthermore, similar to the previously deduced theory that Mana could advance into Divine Power, Dark Mana could also metamorphose into Pitch-black Divine Power after meeting certain prerequisites.
It was just that, to go from Mana to Divine Power—setting aside his own special case—under normal circumstances, one needed to rely on the increase of Falna level to trigger the divine blood residing within the adventurer's body. Using that as a catalyst, it would ultimately drive the growth of the adventurer's status.
However, the method to sublimate Dark Mana into Pitch-black Divine Power was much simpler.
Using a method revealed in the anime from his previous life, it could be described in one phrase: Eat Magic Stones.
Dark Mana resides within Magic Stones, and monsters born in the Labyrinth, regardless of their racial form, actually have no difference in their core essence.
Although devouring the Magic Stones of other monsters would incur some loss, the speed of strength improvement would absolutely exceed the advancement route of the Falna system.
On this point, Filvis was the best proof.
Before she was converted into a Creature, she was a mere Lv.3. Yet, after a few years, her true combat power had already reached the upper tier of Lv.7.
If she were to go all out, she could even exchange a few blows with the 'Fierce' Ottar.
And this was the result of Filvis spending very limited time in the Labyrinth due to her lack of acceptance of her Creature identity.
If it were Levi who had experienced the Banshee's past—leaving aside whether he would launch a fierce revenge against the mad god Dionysus after having a Magic Stone embedded in his body—even if just for the purpose of self-preservation, he would stay in the Dungeon for at least 300 days out of 365 a year.
...Back to the topic at hand.
Holding the two Class Cards, Dress of Heaven and Valkyrie, Levi's efficiency in farming monsters was unmatched by anyone in the entire Lower World.
In just over three days, his Inventory was stuffed full of monster Magic Stones corresponding to the Lv.4 and Lv.5 stages.
In addition to this, in order to accelerate the speed of subsequent Falna level advancement, Levi specifically spent 2 million Valis to draw a Craft Essence from the Lv.3 Type-Moon gacha pool that could significantly increase the drop rate of heart-type materials: 'Portrait of the Barbaric Pseudo-God'.
Just past 2 AM.
The pale-gold-haired young man, who had just fought a 'great battle' with Hestia and Hephaestus, walked out of the bathroom. He then performed a Space Displaced swap with his clone located at the edge of the continent.
Shortly after revealing his figure inside the Elsoth Ruins, the 'Hōgyoku' within his body bloomed with a faint white light.
At this moment, after waiting for five days in total, Levi's Development Ability 'Limit Break' had upgraded to F-Rank.
If he continued without consuming items, the cooling time required for the next metamorphosis would be further extended to 6.4 days.
With a slight movement of his mind, a Law Crystal flew out from his Inventory and merged into the '+' sign behind 'Limit Break' on the character panel.
Accompanied by a flash of soft white light, the Development Ability 'Limit Break' changed from F-Rank to E-Rank.
Next was the second one.
[Limit Break E → Limit Break D]
The third one.
[Limit Break D → Limit Break C]
Then the fourth, fifth, and sixth.
[Development Ability: ...Limit Break S (When using Hōgyoku for Limit Break, consumption and cooldown are reduced by 50%)]
S-Rank is the limit for Development Abilities; even with the aid of the Hōgyoku, there was no way to metamorphose further.
However, a reduction of a full half in consumption was already a very good buff effect.
At the very least, previously, if he wanted to raise his Falna level from Lv.6 to Lv.7, even if he consumed all the blood-type and heart-type materials in his Inventory, the Hōgyoku's cooldown time after the Limit Break would have been as long as 39 days.
Now, it was almost halved to just over 24 days, or he could add another 3 Law Crystals.
Law Crystals are precious; when there is a lower-tier substitute available, one should definitely choose to consume the substitute.
What's more, the activated Hōgyoku currently had an even more critical use.
Levi walked forward and arrived at Filvis's side.
Then he reached out his right hand, his fingertips lightly touching the Magic Stone located on her chest.
In the next second, a notification panel visible only to him quietly appeared:
[Limit Break requires consuming 64,000 (32,000) Mana points. After Limit Break, the Banshee Filvis's Creature Level will rise from Lv.7 to Lv.8. Hōgyoku cooldown: 640 (320) days.]
Levi raised an eyebrow upon seeing this. 'As expected, it works.'
Although the Hōgyoku is a soul equipment, it is not limited to affecting only the equipper themselves.
Aside from Limit Breaking Falna levels, Magic Slots, Development Abilities, and the star ratings of Magic and Skills, it can actually also produce effects on weapons and even other people.
For instance, right now, if Levi were to touch the 'Confirm' button, Filvis's actual combat power would welcome a small upgrade within a short period of time.
But clearly, without using extra items, unless he had water in his brain, such a thing would be impossible to happen.
With a slight movement of his mind, the Limit Break panel dissolved into light.
Immediately following that, a large amount of Magic Stones flew out from his Inventory, landing beside the hospital bed where the Banshee lay.
This time, within the reappearing panel, the Hōgyoku's cooldown time was instantly shortened to 7 hours.
"Tsk—"
Levi clicked his tongue, quickly deducing a scenario in his brain based on known intelligence.
He soon reached a conclusion—if he wanted to raise Filvis's Magic Stone level to Lv.10, and subsequently cause the Dark Mana within it to metamorphose into Pitch-black Divine Power, relying solely on farming monsters to obtain Magic Stones would take at least a month, or even longer.
That being said, Levi still chose to activate the upgrade for the 'Banshee' Creature Level.
In the next second, the Magic Stones piled up like a mountain around them suddenly turned into countless black liquids, surging into Filvis's chest like a tide.
Almost simultaneously, the black-haired elf's originally shattered spirit seemed to receive some nourishment. Her hollow eyes gradually brightened, only to reveal an expression of despair once again the moment she saw Levi.
